The Last September (2000)

In 1920s Ireland, an elderly couple reside over a tired country estate. Living with them are their high-spirited niece, their Oxford student nephew, and married house guests, who are trying to cover up that they are presently homeless. The niece enjoys romantic frolics with a soldier and a hidden guerrilla fighter. All of the principals are thrown into turmoil when one more guest arrives with considerable wit and unwanted advice.
